Per- and polyfluoroaklyl substances (PFAS) of are of interest due to their persistence and ubiquity in the environment and their potential health and environmental effects. While these compounds have been well studied in the past 10 years, little is known about PFAS in oil and gas produced waters, which are voluminous and have the potential to impact the environment through surficial...

Surface Urban Heat Island (SUHI) land surface temperature (LST) data is derived from Landsat thermal band. The LST including annual mean LST (MeanLST) and annual maximum LST (AVEMaxLST). The annual mean LST (MeanLST) therefore represents the average of all clear observations in a specific year. The seasonal maximum temperatures were then averaged to represent the annual mean maximum LST...

A validation assessment of Annual National Land Cover Dataset (NLCD) CONUS Collection 1.0 annual land cover products (1985–2023) for the Conterminous United States (CONUS) was conducted with an independently collected reference dataset. Reference data land cover attributes were assigned by trained interpreters for each year of the time series (1984–2023) to a reference sample of 8,360...

This Annual NLCD Reference Data Product includes the collection of an independent dataset of 8,360 30-meter by 30-meter samples across the Conterminous United States (CONUS). The Annual NLCD Collection 1 sample design was developed as a two-phase collection by a team of image interpreters as follows: an initial base sample containing 5,000 sample plots chosen purely by simple random...

This data set contains Lake Trout (Salvelinus namaycush) egg catch per unit effort (CPUE) estimates obtained from egg traps set on Stony Island Reef in Lake Ontario. These data were collected from sampling efforts in November 2017 and October-November 2019. Stony Island Reef is a cobble spawning reef located in the eastern basin of Lake Ontario and was chosen as the study site because it...

Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS). Here, we present results of a change analysis to estimate shifts in floodplain inundation regime characteristics from 1940 to 2022 in navigation pools 3 through 10 along the Upper Mississippi River. Data were derived from a...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources in the North Arabia provinces. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources...

These data were collected to understand the occurrence of per- and polyfluoroalkyl substances (PFAS) in drinking water samples at selected public water systems in West Virginia identified to have detections for PFAS above laboratory reporting levels in previously collected raw-water samples (McAdoo and others, 2022). These data are stored in the USGS National Water Information System...

An atmospheric river storm on January 9, 2023, produced widespread landsliding in the Santa Ynez Mountains in Santa Barbara County and Ventura County, California (USA). Landslides occurred in the footprint of the 2008 Tea Fire, 2009 Jesusita Fire, 2017 Thomas Fire, and 2019 Cave Fire, as well as in areas that had not burned in more than 15 years. Most of these landslides were shallow...

This dataset includes larval fish catches, species identifications, total length measurements, and relevant covariate data from a larval fish community survey of the U.S. waters of Lake Ontario. Sites were surveyed along a bottom depth gradient of 5 to 225 meters, covering a range of nearshore and offshore habitat between the months of May and July 2024. Vessel and gear descriptions are...

In western United States streams, Oncorhynchus virginalis stomias (Greenback Cutthroat Trout; GBCT) was thought to be extinct; however, a genetically verified population was identified and used for subsequent conservation efforts to reestablish populations. To restore native trout habitat, stream reaches upstream of a dispersal barrier are treated with a piscicide (rotenone) to remove...

Wind has the potential to carry seeds long-distances and could be an important consideration in the management of natural vegetation along the U.S.-Mexico Border with border barrier infrastructure. Shrubs, native grasses, the invasive Pennisetum ciliaris (buffelgrass), soil particles and pebbles dispersed in the ecosystem, especially in maximum wind and/or precipitation events. While...
